What year was the Declaration of Independence adopted?

The Declaration of Independence was adopted in the year 1776, specifically on July 4th. This document marked a pivotal moment in American history, as it represented the colonies' formal assertion of independence from British rule. The adoption signified not only a break from British governance but also articulated the principles of individual rights and the idea that governments derive their power from the consent of the governed. This foundational document set the stage for the development of the United States as an independent nation and has since become a symbol of American ideals and values.
